I was on Mississippi Hwy. 49 North around 7:20 AM on Monday, November 26, 2007 when this Lunatic in a white FORD/Chevy truck decided to pull out in front of ten vehicles in the left lane. When he pulled into our lane he just stopped in the middle of the lane & acted as if noone was behind him smashing their brakes & horns.No 1 could go around him as a result of the right lane was full of cars. Everyone in the left lane had to crash on their brakes to retain from each other & the idiot who pulled out in front of us. To make matters worse, he drove thirty miles under the speed limit holding up traffic.
